[Elecraft] E0400E3 & E0406A6 ERR DSE -- K3

[ken brookner]

I'm getting these errors intermittently--only twice now about a week 
apart.  K3 seems to be working ok, including the SUB.  I reloaded all of 
the firmware after the first instance.  I'll leave the radio on while I 
eat dinner or something and when I come back a couple of hours later I 
might have this error.  I'm using Dxlab's Commander to control the rig.

K3 includes:

KAT3-F
K3/100-F
KXV3A
KRX3-F
KBPF3 (2)
KDVR3

I built my first one, but had the factory build this one.  What do these 
errors mean?  K3 has the latest firmware available through the K3 utility.

Thanks!
